ADM3052BRWZ-RL7 - Isolated CAN Transceiver 5kV | ADI
MPN： ADM3052BRWZ-RL7 ✓ 啟用中ADM3052BRWZ-RL7 概覽
An isolated CAN transceiver is an interface IC that places a galvanic isolation barrier between the logic-side CAN controller and the physical bus-side transceiver. In a CAN node, the controller sends TXD/RXD signals across the isolation barrier to the transceiver, which then drives the differential CANH and CANL bus lines. This prevents ground loops, common-mode voltages, and transient noise in industrial or automotive networks from disturbing the local microcontroller. The transceiver sits in the signal chain between the CAN controller and the twisted-pair bus, making isolation a key reliability requirement in harsh environments.
Key features of the ADM3052 family include 5 kVrms isolation voltage, a 1/1 driver/receiver configuration, 1 Mbps ISO 11898-compliant data rate, and a logic-side supply of 3.3 V or 5 V. The integrated linear regulator enables bus-powered operation from a 24 V-class V+ rail, eliminating the need for a separate isolated DC-DC converter in many nodes. The 16-lead SOIC wide-body package supports surface-mount assembly and automated tape-and-reel production.
From a design perspective, the ADM3052 integrates the isolation barrier, CAN transceiver, and LDO regulation into one package, simplifying PCB layout and reducing component count. The iCoupler technology provides common-mode transient immunity that is critical for reliable CAN communication in motor drives, battery packs, and factory-floor networks. Because the bus side can be powered directly from V+, the node can be designed as a two-wire bus-powered device in applications where a standalone isolated supply is not economically justified.
Typical applications include automotive electronic control units, battery management systems, industrial CANopen networks, building automation, medical monitoring equipment, and test instrumentation. The combination of 5 kVrms isolation and bus-powered regulation makes the ADM3052 especially useful in distributed sensor nodes that must survive ground potential differences.
When designing with this device, pay attention to the input voltage range and dropout of the integrated linear regulator, and place adequate bypass capacitance on the V+ and logic-side rails. The isolation barrier also requires proper PCB creepage and clearance to maintain the specified 5 kVrms withstand voltage.

典型應用
ADM3052BRWZ-RL7 適用於 6 應用s: Automotive ECU and Battery Management CAN Bus, Industrial Automation and CANopen Networks, Battery Energy Storage System Monitoring, Medical Device Monitoring, Building Automation and HVAC Control, Test and Measurement Instrumentation.
Automotive ECU and Battery Management CAN Bus
The ADM3052BRWZ-RL7 fits automotive battery management and ECU networks by providing 5 kVrms iCoupler isolation between high-voltage traction sections and low-voltage control electronics. Its integrated linear regulator lets the node draw power from the bus-side V+ rail, simplifying isolated power generation in distributed nodes. At 500 kbps to 1 Mbps, the transceiver maintains ISO 11898-compliant differential signaling on CANH and CANL. The SOIC-16W package supports rugged automotive PCB assembly, and the common-mode transient immunity of iCoupler technology reduces false bit errors in electrified vehicle environments.
推薦
Industrial Automation and CANopen Networks
In factory-floor CANopen and DeviceNet installations, the ADM3052BRWZ-RL7 prevents ground loops and common-mode noise between PLCs, I/O modules, and motor drives. Its 5 kVrms isolation and bus-powered linear regulator reduce BOM count and simplify the power architecture of remote sensor nodes. The 1 Mbps data rate is sufficient for most discrete and analog I/O automation traffic. By integrating isolation and regulation, the device avoids the need for a separate isolated DC-DC supply, allowing designers to place compact nodes directly on the CAN backbone with predictable EMI behavior.
推薦
Battery Energy Storage System Monitoring
Battery energy storage systems require communication across cells that may sit at significantly different ground potentials. The ADM3052BRWZ-RL7 provides 5 kVrms galvanic isolation and bus-powered operation, allowing CAN messages to pass between battery modules and the central BMS controller without destructive ground current. The integrated linear regulator can power the isolated side from a 24 V auxiliary bus, reducing the need for per-module isolated power supplies. Its 1 Mbps data rate comfortably handles status, voltage, current, and temperature telemetry from stacked battery cells in both stationary storage and EV applications.
推薦
Medical Device Monitoring
The ADM3052BRWZ-RL7 is suitable for medical monitoring systems where patient-connected electronics must be galvanically isolated from hospital network infrastructure. Its 5 kVrms isolation helps break ground loops that could affect sensitive physiological measurements, and the CAN bus provides deterministic communication between patient monitors, infusion pumps, and central stations. The bus-powered regulator simplifies the isolated side by drawing power from the CAN bus V+ rail. With ISO 11898-compliant signaling and 1 Mbps data rate, the transceiver supports real-time vital-sign data streaming while maintaining a compact SOIC-16 PCB footprint.
推薦
Building Automation and HVAC Control
In building automation, distributed HVAC controllers, lighting panels, and access control nodes often share a long CAN bus across different ground planes. The ADM3052BRWZ-RL7 provides the isolation needed to avoid ground differentials while the integrated linear regulator powers the bus side from a local V+ rail, lowering installation cost. The 5 kVrms rating gives margin for lightning-induced transients on exposed building cabling. The device works with 3.3 V or 5 V microcontrollers, making it compatible with low-power building controllers and enabling simple interface to standard CANopen building profiles.
推薦
Test and Measurement Instrumentation
The ADM3052BRWZ-RL7 is used in modular test equipment and data acquisition systems where isolated CAN channels communicate with sensors or actuators under test. Its integrated regulator reduces the number of isolated supplies needed on multi-channel instrument cards. The 5 kVrms isolation protects low-voltage measurement circuitry from transients on the device-under-test bus, and the 1 Mbps ISO 11898 output enables high-speed command and response telemetry. Engineers can place the transceiver on a 16-lead SOIC footprint with simple V+ filtering, achieving a clean isolated CAN interface in benchtop and rack-mount instrumentation.

設計說明
The ADM3052 integrates a linear regulator for the isolated bus side. When powering the node from V+, ensure the V+ input voltage is within the regulator's specified operating range and provide at least a 10 uF low-ESR ceramic capacitor plus a 0.1 uF high-frequency bypass at the V+ pin. The linear regulator dissipates (V+ - Vout) * Iout; at high V+ and high bus-side load, add a copper pour or thermal via plane around the SOIC-16W package to keep junction temperature within limits.
Maintain the isolation barrier gap on the PCB according to the ADM3052 datasheet recommendations. For a 5 kVrms isolated CAN transceiver, the creepage and clearance distance between the logic-side ground plane and bus-side ground plane must be sized for the target safety standard. Do not route copper traces under the device across the isolation boundary. Keep the CANH and CANL differential pair tightly coupled and place the termination resistor close to the transceiver for reduced signal reflection and EMI.
The integrated linear regulator makes the SOIC-16W package dissipate more heat than a plain transceiver when V+ is much higher than the regulated bus supply. Calculate worst-case power dissipation as (V+ - Vreg) * I_bus. The SOIC-16W package has moderate thermal resistance; in high ambient temperature industrial cabinets, add a 1 oz or 2 oz copper pour on the top and bottom layers and use thermal vias to the ground plane. If dissipation exceeds 1 W continuously, evaluate the ADM3054 signal-isolated version with an external DC-DC.
